Imagine a system consisting of a set of 5 sub-sytems in series. • Each subsystem has 2 components in parallel. • Assume for simplicity that all 10 components are identical • All component lifetime ~ Exponential(mean=1,000 hr). Use simulation to estimate the pdf of system lifetime.

The operation is suck a c@ck? !

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
